Transcript of Cell Analogies Collage

T.J. Wilkins
Period 4 Cell Analogies Collage THIS CELL IS AN ANIMAL CELL Analogy- the nucleus is like a brain
because it controls and coordinates
activities for the whole cell like a brain controls and coordinates activities of
the body. Nucleus- regulates all cell activity. Analogy- the golgi apparatus is like the post office because it packages things (proteins) and sends them to the correct location like a post office packages letters and sends them the correct address. Golgi Apparatus- involved in modifying and packaging proteins into vesicles to be sent to other parts of the cell. Analogy- the ribosomes are like a restaurant because they are responsible for creating proteins or things that the cell needs or consumes like a restaurant is responsible for creating food that people use to fuel their body to carry out other functions. Ribosomes- responsible for protein synthesis. cell membrane Analogy- the cell wall is like the walls of a house because it maintains the shape and allows things to pass through it like the walls of a house provide structure and support and allow things to enter through doors and windows. Cell or Plasma membrane- a thin lipid bilayer enclosing the cytoplasm of the cell, that regulates what enters and leaves the cell Cell Wall- a rigid layer of polysaccharides enclosing the membrane of a plant cell; provides support. Analogy- cytoplasm is like the jello in a fruit jello cup because it holds things in their place and provides support fro the cell like the jeelo in a fruit fello cup holds the fruit in its place and provides support. Cytoplasm- the entire contents of the cell, exclusive of the nucleus,and bounded by the plasma membrane. Offers support to the cell and speeds up inter-cellular travel. Analogy- chloroplast is like a solar panel because it absorbs sunlight in order to perform photosynthesis and creates energy or food for the plant cell like a solar panel absorbs sunlight and transforms it into energy for people to use. Chloroplast- organelle found only in plant cells that absorbs sunlight and uses it to drive the synthesis of organic compounds from carbon dioxide and water. Analogy- chromatin is like a library because it stores information about genes/ DNA and hold the information the nucleus needs, like a library holds the information we need to do our work. Chromatin- the complex of DNA and proteins that make up a eukaryotic chromosome. When cell is not dividing, chromatin exists in a mass of very long, very thin fibers. Packs DNA into tight/little volumes in order to be stored in the nucleus. Analogy- the centriole is like a separated craft supply, because it organizes different parts of the cell like a separated craft supply holder organizes different craft supplies into their own bin and places things where they need to be for future use. Centriole- organize cilia, flagella and other microtubules Analogy- the cytoskeleton is like rebar in concrete because it gives the cell its shape and support like the the rebar in concrete gives support and shape to the concrete. Cytoskeleton- supports the cell and provides shape; aids movement of materials in and out of the cell. Analogy- The cell membrane is like an colander because it regulates only allows small particles that are the right shape pass through while creating a seal to hold other parts back. Nucleolus- contains RNA for protein manufacture Analogy- the nucleolus is like a copy machine because it produces copies of the RNA to be used in the cell, like a copy machine makes copies of the original and sends out the copies to be used elsewhere Cila- move the cell from one place to another using small hairs that move in a rowing motion. Analogy- cila is similar to an earthworm because it uses small hairs to move the cell from one spot to another like an earthworm uses tiny hair like structures to move throughout the soil. Mitochondria- controls level of water and other materials in the cell; recycles and decomposes proteins, fats, carbohydrates, and is responsible for cellular respiration. Analogy- the mitochondria are like a power plant
because it uses food and oxygen to produce energy and carry out respiration, like a power plant uses coal to burn and produce energy to use in homes. Flagellum or Flagella- move the cell from one location to another using a tail-like structure. Analogy- the flagella is like the legs of a human
because it orchestrates the cells movement from one location to another like legs transport humans from one place to another Lysosome-digests old organelles that are no longer useful to the cell. Analogy- a lysosome is like a garbage truck/ dump because it gets rid of old parts of the cell that are no longer needed, like a garbage truck gets rid of unneeded waste from your home. Vacuole-stores things that the cell
needs (water, nutrients, etc.). Endoplasmic Reticulum- produces various materials for the cell and moves things through the cell.
Smooth- involved in synthesis of lipids and hormones
Rough- involved in protein synthesis Nuclear Envelope- facilitates and regulates the exchange of materials between the nucleus and the cytoplasm. Analogy- the nuclear envelope is like a football helmet because it protects the nucleus (or brain) and lets important information get in and out like a football helmet protects the head and brain and has "pores" like ear holes to let information in and out so the brain can process it Analogy- the endoplasmic reticulum is like a factory because it produces a variety of things the the cell uses including proteins, lipids, etc., like a factory produces a variety of things that humans need and use. Analogy- the vacuole is like a storage facility
because it stores things the cell needs like a
storage facility stores things that humans need. THE END PLANT CELL cilia flagella chromatin
